Generalized Rainbow Differential Privacy

no code implementations11 Sep 2023 Yuzhou Gu, Ziqi Zhou, Onur Günlü, Rafael G. L. D'Oliveira, Parastoo Sadeghi, Muriel Médard, Rafael F. Schaefer

In this framework, datasets are nodes in a graph, and two neighboring datasets are connected by an edge.

Rainbow Differential Privacy

no code implementations8 Feb 2022 Ziqi Zhou, Onur Günlü, Rafael G. L. D'Oliveira, Muriel Médard, Parastoo Sadeghi, Rafael F. Schaefer

We extend a previous framework for designing differentially private (DP) mechanisms via randomized graph colorings that was restricted to binary functions, corresponding to colorings in a graph, to multi-valued functions.

Broadcast Rate Requires Nonlinear Coding in a Unicast Index Coding Instance of Size 36

no code implementations2 Feb 2021 Arman Sharififar, Parastoo Sadeghi, Neda Aboutorab

Insufficiency of linear coding for the network coding problem was first proved by providing an instance which is solvable only by nonlinear network coding (Dougherty et al., 2005). Based on the work of Effros, et al., 2015, this specific network coding instance can be modeled as a groupcast index coding (GIC)instance with 74 messages and 80 users (where a message can be requested by multiple users).

On Monotonicity of the Optimal Transmission Policy in Cross-layer Adaptive m-QAM Modulation

no code implementations21 Aug 2015 Ni Ding, Parastoo Sadeghi, Rodney A. Kennedy

We also show that, due to the L-natural-convexity of DP, the variation of the optimal policy in queue state is restricted by a bounded marginal effect: The increment of the optimal policy between adjacent queue states is no greater than one.

Structured Optimal Transmission Control in Network-coded Two-way Relay Channels

no code implementations29 Oct 2013 Ni Ding, Parastoo Sadeghi, Rodney A. Kennedy

This paper considers a transmission control problem in network-coded two-way relay channels (NC-TWRC), where the relay buffers random symbol arrivals from two users, and the channels are assumed to be fading.
